This genus was figured by Ulysses Aldrovandus (Mus. Metall., pi. 16) in 

 1648, and by Lister (An. Angl., p. 214) in 1678, both being, of course, fossil 

 forms. It seems to have been overlooked until now that we are indebted to 

 Sowerby for its characterization, and that he is entitled to be cited as authority 

 for the genus.
